摘要
研究了将AlRETiB+ +N+ 注入后H1 3钢表面性能的变化。纳米硬度分析表明 ,AlRETiB+ +N+ 的注入使H1 3钢表层纳米硬度从 1 3 37GPa增加至 1 9 90GPa。刻痕试验表明 ,注入试样表面结合强度发生了变化 ,形成“硬壳”。SEM观察发现注入层性能与基体性能差别很大。从X光电子能谱发现 ,注入后 ,Ce峰位、La峰位、N峰位发生较大位移 ,生成的化合物极其复杂 ,为未知化合物 ,并有BN。
By AlRETiB and N ions implantation,surface layer properties of H13 steel has been modified.The Nano indentation results showed that hardness is from 13 37GPa up to 19 90GPa after AlRETiB and N ions implantation,The score experiment showed that binding strength of the surface layer was changed and it formed into a 'hard shell'.SEM analysis show that there differences between surface layer and base.XPS results showed that significant shift of Ce,La and N peaks,resulting in formation of complex unidentified compound together with BN and AIN.
